This invention relates. to a brick-making machine and has foritsgeneral' object to pro vide a novel machine especially adapted formaking water struck brick and which em bodies in its constructionvarions" novel ,fe'atnres all as will be more fully hereinafter set a i.v.

In order to give an understanding of the invention I have illustratedinthedrawings a selected embodiment thereof which will now be" describedafter which the novel features will be pointed out in'the''app'endedclaims.

Howeveryit is notan essential featiire of the inventionthat these operative parts should be? mounted "upon a movable car or'truck. i i

The feed chamber which; receives the clay and from which it. is 'fed'into the molds is indieated generally at '3. This chamber is open at itsbottom, said chamber being herein show-n as having siX openings 4;therein eac h openingcorresponding'to'one mold ofa gang 0t molds. Thismachine is constructed to mold six bricks at one time b utlof ooiirs'e,it will b'eunderstood that theisi'ze of' th e chamber 8 and the numberof bricks ,whic'hz are molded at oneoperation can be varied without inany way departing fromthe' invention. Operating in the chamber 3 is apliinge'r or presser'member 5 which by, itsdownward movement serves to"force the clay in the chamber 30st through the discharge open, ingsf.The clay is fed into the chamber 3 through an inlet opening 6' bymeans'lwhich willbel presentlyv described .andQI' will also laterdescribeth'e mechanism s e ming the'plunger 5 "The gang mold in whichthe bricks are molded is indicated at 'Z'Qthis moldhaving a pluralityofmold cavities 8 each adapted; to mold a brick and there'heling onecavity for each ofthe discharge openings 41 i r This mold member ismounted on and carried by a mold carrier 9 which .is herein shown asprovided with wheels 10 that oper ate on supporting rails ll with whichthe truck or ,car 1 'is provided; "This carrier or carriage 9.is adaptedto move from the full to the dotted line position in Fig. 5. hen

a board 12 which forms the bottom of the mold cavities and which is alsoremovable from the carriage 9.

Means are provided for operating the plunger 5 and the carriage 9 intimed relation so that theplunger will be given its downwardor'operative movement when the carriage is in the dotted line positionFig.5 and will be retracted when the carriage is in the full lineposition.

Situated beneath the mold carriage 1 is an operating shaft 13 whichextends longitudinally of the car 1 and is mounted in suitable bearings14 secured. to the car. This shaft is given an oscillating motion andconnections are provided between it and both the plunger 5 and thecarriage 9 so that both of these parts are operated thereby.

YVhile any suitable means for driving or operating the shaft may beemployed I have herein shown for this purpose an electric motor 15 whichis suitably mounted on the car 1. This motor is connected by a drivingbelt 16 to a driving pulley 17 mounted on a shaft 18, said shaft beingin turn connected to a shaft 19 through suitable reducing gear ingherein shown as two intermeshing gears 20 and 21 mounted on the shafts18 and 19 respectively, the gear 20 being smaller than the gear 21.

The shaft 19 has a sprocket wheel 22 thereon which drives a sprocketchain 23 that runs over another sprocket wheel 24 loosely carried on acrank shaft 25 but which is adapted to be clutched to said crank shaftby a suitable one-revolution clutch. The crankshaft is provided with acrank disk 26 to which is connected one end of connecting rod 2?, theother end of said rod being connected to an arm 28 that is fast on theshaft 13. The rotation of the crank disk 26 will thus give to the shaft13 the required oscillating movement to operate the plunger 5 and thecarriage 9. r 7

Theplunger 5 is connected through a connecting member 29v to theintermediate. porion of a lever 30, said lever being pivoted, at oneendto the car as shownat 31 and having connected to its other end a link32 which in turn is connected to an arm 33 fast on the shaft 13. Theoscillating movement of the shaft 13 will thus reciprocatethe link 32 ina vertical direction thereby swinging the lever about its pivot 31. Thislever is shown as having-a return spring-34 secured thereto which tendsto raise it and hold it in its raisedposition and the free end of thelever is shown as beingguided in a suitable guide 35 carriedby thecar 1. j j

The downward swinging movement of the lever 30 will operate through 29to force the plunger 5 downwardly thereby to force clay from the chamber3 into the mold cavities s v Y 'I have statedabove that the carriage 9is the connection also connected to and operated by the shaft 13. Forthis purpose said shaft has fast thereon a plurality of arms 36 to eachof which is connected one end of a connecting rod 37, the other end ofeach rod being pivotally connected to the carriage 9 as shown at 38. Theoscillating movement of the shaft 13 will thus also reciprocate thecarriage 9.

The carriage 9 is provided with a plate 39 which'closes the dischargeopenings '4 when the carriage is in the full line posit-ion, said platebeing withdrawn from beneath the openings 4 when the carriage is in thedotted line position. I The mechanism above described is so constructedthat the plunger5 is moving clownwardly asthe carriage moves from thefull to the dotted line position while the-plunger has itsupwardmovement during the time that the carriage is moving from the dotted tothe full line position. Consequently as the carriage begins to move intothe dotted line position the plunger begins its downward movement and assoon as the plate 9 begins to uncover the discharge openings 4 the clayin the chamber 3, which has been put under compression, will be forcedthrough said openings 4 into the mold cavities 8.

The chamber 3 is herein shown as located on the outside of the car andthe plunger 5 is provided with the upstanding guide element 40 whichoperates in ways 41 that are secured to thecar. The walls 42 of thechamber 3 are preferably lined with steel plates 43, and the plunger 5is provided with me tallic wear plates 88 which engage the steel plates43. These wear plates 88 are adjustably mounted on-the plunger 5 and arefor the purpose of maintaining a tight joint between the plunger and-thewear plates 43, this being for the purpose of reducing wear and thusmaintaining a tight joint between the periphery of the plunger 5 and thewalls of the chamber. I

The connection 29 between the operating lever 30 and the plunger '5 isin adjustable connection arranged so that the clay in the chamber 3 maybe subjected to different degrees of pressure depending upon itscondition. This connection comprises the lower twin section 44 whichisrigid with the plunger 5 and the upper section 45 which is pivotallyconnected to the lever 30 through the medium of the :link .46. Theupper'section 45 is located between the two parts of the twin section 44and said section'45 is pro vided with a slot 47 in which is received aguiding vpin48 carried by the twin section 44. This twin section '44 isformed with a. plurality of apertures 49 in any one of which a stop pin50 may be inserted.

Inthe operation of the device when. the lever 30 is swung downwardly theupper'section 45 of-the connection 29 will be carried.

45 p The inner endof eachihlade isprovided with w ee? downwardlyrelatiye to the ,tavin section 1 hi throughithe dischargeopenings 4.

clutch to become engaged. The operator may then release the lever 81 andthe spring 82 will return the clutch dog 69 to its operative position sothat when the shaft 25 completes its revolution the clutch will beautomatically disengaged. i In addition to the clutch above described Ihave also provided a clutch 83 by'which the pulley 17 is clutched to theshaft 19,, said clutch 83 having an actuating lever 84 by which it maybe manipulated. When the clutch 83 is disengaged then the entiremechanism will be idle. The clutch comprising I the clutch members 65,66, however, merely controls the oscillation of the the parts operatedthereby. H

In the making of water-struck brick it is necessary to keep the mold wetand I have provided herein a tank 86 into which the mold 7 may be dippedjust before it is placed on the mold carrier and thereby providing thenecessary wet mold for the reception of the clay. This tank maybe keptfilled with water from a supply pipe 87.

The chamber 3 is provided with a clean-out opening that is normallyclosed by a door or panel 85. This door, however, can be readilyopened'whenever it is necessary to obtain access to the chamber.

I have shown the rails 11 as supported on adjustable supports 89, thepurpose of these being to provide for adjustingthe rails if suchadjustment is necessary in order to maintain'a tight joint between theplate 39 and the bottom of the chamber.

While I have illustrated herein a selected embodiment of the invention Ido not wish to be limited to the constructional features shown.

I claim:
